NOVELTY - Method for producing nanocellulose films or fibers, involves (a) providing a gellable nanocellulose dispersion comprising a nanocellulose and water, where the gellable nanocellulose dispersion comprises 0.1-5 wt.% total dry matter relative to the total weight of the gellable nanocellulose dispersion, and the nanocellulose constitutes 10-100 wt.% of the total dry matter, (b) extruding the gellable nanocellulose dispersion through an extrusion die into a coagulation liquid to provide a strip of nanocellulose gel, and (c) removing water from the strip of nanocellulose gel to obtain the product. USE - The method is used for producing nanocellulose films or fibers (claimed) e.g. barrier films. ADVANTAGE - The method provides rapid, effective dewatering of the films or fibers may be achieved using relatively cost-effective dewatering means and provides uniform dispersion and avoids premature floc formation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the nanocellulose film or fiber comprising 10-100 wt.% nanocellulose by dry weight.
